G. K. CLARK. MOTOR ATTACHMENT. APPLIoATIoN Hmm Nov. 2a, 1911.

Attorneys Be it known that. 1,' Guy K. CLARK, a citizen of the United States, residing at Canon City, in the` county of Fremont-and State of Colorado, have inventeda new and useful Motor Attachment, of which the following is a specification.'

The resent invent-ion aims to provide mechanism yfor rewinding the film employed yi'nja moving "pictureilnachine, and to provide a noveljmeansnwhereby the film may be wipedcleanfasit passes from one reel to another.

T ."With the'l foregoing :andi thel" i Objects ini view, which will appear as the description proceeds, thel invention resides in A the combination and arrangement of parts and inthe details ofv construction hereinafter described and claimed, it being understood that changes in the recise embodiment -offinvention herein disclosed can be made within" the" 'scopefof what is claimed .without departing from the spirito-f the invel'liSiOliL` i In the accompanying drawings, Figure 1 shows the invention in sidel elevation; l4`ig. 2 is a transverse section on thelin'ej2-2- of Fig. 1.

The supporting structure embraces 'as a primary element, a base 1, fixed to and rising from one end of which, is a standard 2. Secured to the op osite end vof thebase 1, is a receptacle 3, e same preferably comf risingV anouter .box 4, ordinarily fashioned om wood, the box` 4 being lined, aloner its.

, sides and upon its bottom, with a re ractory material. This lining 5 may be fashioned from metal, asbestos or the like'. The

` receptacle 3 is closed by a lid 6, hingedly 4o,

connected with the receptacle as shown at 7. The 'invention further includes an open, rectangular frame 9, one end of which is united by' means of a securing member 11,v with the standard 2, the other end wall of the frame 9 being secured to the box 1; The motor 15, preferably electrically operated, is mounted within the receptacle 3.. T he lining 5 'serves to prevent oonagration, resulting from an improper operation of themon tor 15. The invention further includes spaced primary and secondary shafts, 20 and 21, respectively, the shafts 20V and '21 being mounted forirotation inthe frame 9.`V J ouron' the ,primary ivro'ro'e ATTACHMENT.

21 is a pulley 36, about which 'is trained a belt 37, extended through an opening 38 in 'the receptacle 3,.the belt 37 being operatively connected with the motor 15. Fixed to the secondary shaft 21, and located between the pulley 36 and the frame 9, is al pinion 39, meshing into a pinion 110, secured to -a winding shaft 41, journaled for rotation' in the :trame 9. Y l

' Mechanism is provided for clean-ingthe film 35, as it 'passes from the primary reel 31 to the secondary reel 32. This mechanism comprises a rack, including, as most clearlyshown in 2, a base 56, from the 'ends of which, upright arms 57 and 56 extend. The base 56 of the rack is notched to. form seats 59, adapted to receive the side portions' of the frame 9, as clearly shown in Fig. 2, and 'securingelements 60 are extended-through the lower ends of the arms 57 and 58, into engagement wththe side portions of the frame 9.

In their adjacent fassa-'and at their up` lper ends, lthe arms 57 and 58 are equipped with guides 61, the lower ends of which constitute shoulders 62, which shoulders are locatedv well above the axes of the shafts 2 0 and 21. Slidably mounted vin -the guides 61, and normally resting against the shoulders 62, is a lower clamp block 63. An upper clampl block 64 is mounted for sliding movement in the guides 61, above the lower I clamp blocks 63 and 64 are rounded and over these rounded surfaces are secured resilient, yieldable facings 65, preferably fashioned '.from velvet or the like. Secured to the upper face of thev upper clamp block 64 is a thrust block 66, adapted to receive the lower end of a 4screw 67, threaded .into the intermediate portion of a latch bar-.68,one 'end of which-is pivoted as shown at 69 to the arm 57, the .free end of the latch bar 68 having an opening, adapted to receive the vupper end of the-arm 59, there being a wing screw '71 threaded` into the free end of the latch' bar 68, the wing screw being ada ted to engage the arm 58, to hold the lato bar 68 in place. 31, ga--eecondar3tf 1x1-practical lope'ratio'ni, when the motor 15 bloclr63. The meeting faces of the reel to the other, will move between the re` silient facings 65 which are carried by the clampbloclis 63- and 64, any dust or other material which may haveaccumulated upon the film, being swept away by the facings 65. '*By4 adjusting the ,tension of the set scr'w 67,. the relative positions of the bars 63 and 64, and consequently the pressure of:a

the facings 65 against the film 35 may be adjusted, When it is desiredto remove one or both of the clamp blocks F13-64, the screw 71 may be manipulated to set free the movable end of the latch bar 68, whereupon the latch bar may be swun upwardly upon its pivotal mounting 69, tins setting free the clamp blocks 63 and 64, so that the same may be removed upwardly, out of the guides 61. As will be readily understood, the latch bar 68 may be employed as a manually operable lever, whereby 4the pressure exerted by t-he upper block 64 against the lower block 63, may be increased, temporarily, to clean a length of ilm which is soiled by an unusually tenacious material. It is to be noted thatl the shoulders 62 are located above the axes of the shafts 21 and 2Q, and thus as clearly shown in Fig. l, the lm 35 will be led ofi' the upper portions of the rolls which the reels 31 and 32 carry. intermediate portion of the ilm will, therefore, be depressed to a minimum extent, and

Thev

consequently the intermediate portion of the film will not be bent sharply over the lower surface of the upper clamp block 64. Undue wear upon the film vwill thereby be avoided, only so much pressure asis necessary for cleaning, being applied by manipulating the set screw 67, or by manipulating the latch member 68 leverwisie.

Having thus described .the invention,

`what is claimed is In a machine for winding and cleaning moving picture films, a' frame; reel holding shafts journaled in the frame.; oppositely disposed arms fixed to and rising from the frame between the shafts, thearms beingprovided in their adjacent faceswith guides; a lower clamp bar slidable vertically inthe guides and held against horizontal move nient by the guides, the lower clamp bar being upheld by the lower lends of the guides; an upper clamp bar slidable in the guides above the lower clampy bar and held against horizontal movement by the guides; yieldable facing .upon the' bars, between which the film is adapted to pass, a latch bar pivoted to one arm and coperating with the other arm; locking means for uniting the latch bar with' said other arm; and a member adjustable in the latch bar, transversely of the latch bar, and adapted to engage the upper clamp bar to secure a cooperation between the facings.

In testimony that I claim the foregoingy as my own, I have hereto alixed my s1gnature in the presence of two witnesses.
